无法使用注入器注入Play的WSClient实例 [英] Failing to inject Play's WSClient instance using injector

问题描述

我有一个注入了WSClient依赖项的类:

I have a Class that has a WSClient dependancy injected:

@Singleton
class MyApiService @Inject() (wsclient: WSClient, conf: Configuration) {
...
}

以及在运行测试并使用注入器创建MyApiService实例时:

and when running test and creating instance of MyApiService using injector :

class MyTest extends FreeSpec with OneAppPerSuite with ScalaFutures with WsScalaTestClient {

  implicit lazy val materializer: Materializer = app.materializer

  lazy val wsc: WSClient = app.injector.instanceOf[WSClient]
  lazy val conf: Configuration = app.injector.instanceOf[Configuration]

  val myApiService: MyApiService = app.injector.instanceOf[MyApiService]

  "Api Test" in {
    ...
  }

我收到此错误:

异常或错误导致运行中止:无法配置，请参阅 以下错误:

An exception or error caused a run to abort: Unable to provision, see the following errors:

1)注入构造函数java.lang.NumberFormatException时出错: 格式错误10000 at play.api.libs.ws.ahc.AsyncHttpClientProvider.(AhcWSModule.scala:40) 在 play.api.libs.ws.ahc.AsyncHttpClientProvider.class(AhcWSModule.scala:39) 在定位play.api.libs.ws.ahc.AsyncHttpClientProvider的同时 找到play.shaded.ahc.org.造成原因: java.lang.NumberFormatException:格式错误10000

1) Error injecting constructor, java.lang.NumberFormatException: format error 10000 at play.api.libs.ws.ahc.AsyncHttpClientProvider.(AhcWSModule.scala:40) at play.api.libs.ws.ahc.AsyncHttpClientProvider.class(AhcWSModule.scala:39) while locating play.api.libs.ws.ahc.AsyncHttpClientProvider while locating play.shaded.ahc.org. ... Caused by: java.lang.NumberFormatException: format error 10000

，然后在我的application.cong中添加:

  ws.timeout.connection = 10000
  ws.timeout.idle = 10000
  ws.timeout.request = 10000

试图更改为60000，没有区别...

tried to change to 60000 theres no difference...

使用play 2.6.0和scala 2.11.8

using play 2.6.0 and scala 2.11.8

也许有人知道为什么会失败?

someone maybe know why is it failing?

谢谢

推荐答案

我遇到了同样的问题.这是ws.timeout属性的格式问题.

I was having this same problem. It is a formatting issue with the ws.timeout properties.

在Play 2.6中，这些属性必须具有时间单位.这是一个示例配置

In Play 2.6, those properties are required to have a time unit. Here is an example configuration

WSConfigParser尝试使用这些属性中的值构造一个scala.concurrent.Duration实例.持续时间将引发异常如果提供的值没有有效的时间单位.

WSConfigParser tries to construct an instance of scala.concurrent.Duration with the values from those properties. Duration will throw an exception if the values provided do not have a valid time unit.

解决方法是将ms添加到这些属性-> 1000ms

The fix is to add ms to these properties -> 1000ms

这是我的application.conf

This is my application.conf

play {
  ws {
    timeout {
      connection: 10000ms
      idle: 30000ms
      request: 60000ms
    }
  }
}
